Abstract

Method of repairing a winding in a generator, the generator having a generator rotor and a generator stator, wherein the generator rotor and/or stator comprises a plurality of windings, the windings comprising a stack of turns of a conductor around a tooth, wherein the method comprises cutting the winding on a side of the tooth to separate the winding in two parts; removing the two parts of the winding from the tooth; sliding a substitute partial coil on the tooth, the substitute partial coil comprising a stack of incomplete conductor turns having a first end and a second end, said first and second end positioned on the same side of the tooth; and connecting the second ends of each incomplete turn with a first end of the next incomplete turn using a plurality of conductor portions. The disclosure further relates to a kit for making a substitute coil.
